VBScript：具有多个名称空间的XPath查询

Question

什么XPath我应该使用查询来访问GetLogisticsOfferDateResult节点？ 我附加了我正在使用的vbscript。 我怀疑问题与文档中的多个名称空间有关。但是，如何引用XPath中的第二个命名空间？

Dim responseXML 
responseXML = '"<s:Envelope xmlns:s=""http://schemas.xmlsoap.org/soap/envelope/""><s:Body><GetLogisticsOfferDateResponse xmlns=""http://schneider-electric.com/OrderEntryService""><GetLogisticsOfferDateResult>2010-07-20</GetLogisticsOfferDateResult></GetLogisticsOfferDateResponse></s:Body></s:Envelope>"' 

Dim responseDoc 
Set responseDoc = WScript.CreateObject("MSXML2.DOMDocument.6.0") 
responseDoc.loadXML(responseXML) 
responseDoc.setProperty "SelectionNamespaces", "xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'" 
Dim requestedNode 
'This node is not found 
'Set requestedNode = responseDoc.selectSingleNode("//s:Envelope//s:Body//GetLogisticsOfferDateResponse//GetLogisticsOfferDateResult") 

'This node is found 
Set requestedNode = responseDoc.selectSingleNode("//s:Envelope//s:Body") 
'This node is found 
'Set requestedNode = responseDoc.selectSingleNode("//s:Envelope") 

If requestedNode Is Nothing Then 
    WScript.Echo "Node not found" 
Else 
    WScript.Echo requestedNode.text 
End If 

Set responseDoc = Nothing 
Set LODateNode = Nothing 

Answer 1

原来我selectionNamespaces的设置必须如下：

responseDoc.setProperty "SelectionNamespaces", "xmlns:sc='http://schneider-electric.com/OrderEntryService' xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'" 

然后XPath查询必须是：

Set requestedNode = responseDoc.selectSingleNode("//s:Envelope//s:Body//sc:GetLogisticsOfferDateResponse//sc:GetLogisticsOfferDateResult")

你有没有在你的代码中定义的文件（http://schneider-electric.com/OrderEntryService）的默认命名空间。

responseDoc.setProperty "SelectionNamespaces", "'http://schemas.xmlsoap.org/soap/envelope/' 'http://schneider-electric.com/OrderEntryService'" 

您可能需要添加它，或者用属于它的元素前缀。
